Hmm ... now you basically have 4-5 tile formats Wall: 120x60/about 100/60 and on the opposite wall on average 75x60 Floor: 60x60 Shower: 120x30 How about swapping the floor/wall tile formats?
For comparison, here are 2 drawings again with the large tiles (120 x 60) on the floor and the small ones (60 x 60) on the wall, so that everything has been tried out :D

Do the different sizes really stand out that much? Unfortunately, I have little imagination for that.
